That's not the comparison
Yes, an ordinary wood frame house is relatively safe. They have relatively low loads for their materials & construction. Even if you're in 1 that gets totaled, you're likely to survive inside it. But the comparison here is between newer tall, steel frame buildings vs older, short, masonry construction buildings. A really tall building is never monolithic no matter how it might look. It's a steel frame with relatively thin floors & even thinner walls.
